Researchers have developed Tuna-2, a novel unified multimodal model that bypasses traditional vision encoders for visual understanding and generation. By directly processing pixel embeddings, Tuna-2 simplifies architecture and enables end-to-end optimization from raw pixels. Experiments indicate that this pixel-space approach achieves state-of-the-art results on multimodal benchmarks, outperforming latent-space methods in generating high-quality images and demonstrating superior multimodal understanding, especially for tasks requiring detailed visual perception.
